The Clutch Delay Valve sits between the
clutch line and slave cylinder; with the OEM CDV, no matter how slowly,
softly, or smoothly you try to released the clutch there will always be
a delay. In turn causing even the most experienced drivers to look like
amateur drivers. After the stock CDV is replaced with the CDV, you will be able to shift your car like a normal car.

Because of this valve, no matter how
quickly you lift your foot off the clutch pedal, the clutch engages the
flywheel at a constant (slow) rate. In theory, it can save the
driveline from shock, were an inexperienced (or immature) driver to dump
the clutch at high RPM. But in practice, all it does is prematurely
wear out the clutch and turn experienced drivers into people who,
despite 20 years of practice, cannot shift gears smoothly.
